Pierre Humbert

Postdoc in probability and statistics

 

Since September 2021, I am a postdoc in the probability and statistics team of the Laboratoire de Mathématiques d'Orsay (LMO) with Sylvain Arlot. I am also a member of the INRIA Celeste team.

Before that, I completed a PhD at ENS Paris-Saclay entitled Multivariate analysis with tensors and graphs - application to neuroscience, under the supervision of Nicolas Vayatis, Laurent Oudre, and Julien Audiffren.
